Application January 7, 1947, Serial No. 720,666 (o1. 216-29) 9 Claims. 1

This invention relates to new and useful improvements in a gummed tapeapplier, and has particular reference to a portable, hand operablegummed tape applier.

The principal object of the present invention is the provision of a handoperable gummed tape applier whereby gummed tape contained on a rollwithin said applier is pulled from said roll, moistened, applied to apackage or other surface under pressure, and cut off at any desiredlength.

Another object is the provision of a gummed tape applier adapted to beused in any desired position, and to apply tape even to vertical oroverhead surfaces.

Further objects are economy and ruggedness of construction, andsimplicity and dependability of operation.

With these objects in view, as well as further objects which will becomeapparent during the course of the specification, reference will be hadto the drawings, wherein:

Figure l is a side elevation of a gummed tape applier in operativerelationship to a package, shown in the tape applying position in solidlines and in the tape cutting position in dotted lines.

Fig. 2 is a vertical mid-section of the tape applier shown in Figure 1.

Fig. 3 is a sectional view taken on line IIIIII of Figure 2.

' Fig. 4 is a fragmentary vertical section taken on line IV-IV of Figure2.

Fig. 5 is a fragmentary horizontal section taken on line VV of Figure 4.

Fig. 6 is an enlarged fragmentary vertical section taken on line VIVI ofFigure 1.

Fig. 7 is an enlarged fragmentary side elevation of the forward portionof the reservoir handle, detached from the applier frame.

Fig. 8 is a vertical section taken on line VIII VIII of Figure 7.

Like reference numerals apply to similar parts throughout the severalviews, and the numeral I0 applies to a frame comprising a single pieceof sheet metal bent to form two spaced apart side walls I2 joined by aconnecting portion M at the upper edge thereof.

A shaft I 6 extends between and is rotatably carried by side walls !2adjacent'the forward edges thereof, and a pressure wheel i8 is rigidlymounted on said shaft between said side walls. The rim 20 of said wheelis of greater width than the gummed tape to be applied, and carries atire 2.2 of rubber or other soft, resilient material. Said tire iscrowned slightly in order that tape passing around said wheel will seekcenter.

2 A shaft 24 extends between side walls l2 and fixed thereto adjacentthe rearward edges thereof, carries for rotation a moistening roller 26.Said roller comprises a hub 28, a plurality of spaced stiffener discs 36rigidly fixed to said hub, and a quantity of wicking 32, or similarmaterial, filling the space between said discs and extending outwardlypast the edges of said discs. Roller 26 is positioned to engage wheel I8with a light pressure.

Two spool support arms 34, clamped at their lower ends to side walls I2at the upper edges thereof by means of bolt 36, extend upwardlytherefrom. An axle 38 extends between and is supported bythe upper endsof said support arms, said axle being adapted to pass through the hub ccof a spool 42 of gummed paper tape. Said spool is centered on said axleby a spacer washer 44 and friction disc 46, said washer and disc beingcarried on said axle on opposite sides of spool 42, as shown in Figure6. Said friction disc is compressed between hub 40 and a support arm 34,and serves to maintain a tension in the tape as it is unrolled from saidspool.

From said spool, tape 50 is passed through a centering guide 48 carriedon bolt 36. Said guide, as shown in Figures 4 and 5, comprises aU-shaped member of a slightly greater width than tape 58. Bolt 36 passesthrough the legs of said guide, and said guide is centeredlongitudinally on said bolt by means of a pair of spacer bushings 52.

A U-shaped blade support 54, the forwardly extending legs of which arepivotally attached to side walls 12 adjacent the lower forward cornersthereof, carries at its rearward edge a centrally mounted blade 56, saidblade extending upwardly and havingat its upper edge a notched cuttingedge 58 parallel to the shaft 1 6 of wheel !8. Said blade is adapted bythe pivotal movement of support 54 to be moved into contact with wheell8 at. a point just below the point of contact between wheel l8 androller 26. Notches are cut in the lower edges of side walls [2 to permitfree movement of blade support 54. The pivoting arc of said blade awayfrom wheel i8 is limited by stops 62, cut from the forward edges of sidewalls l2 and bent outwardly to extend above and limit the upwardmovement of the extended forward ends of blade support 54.

A reservoir handle 64 is removably attached to frame It by means ofscrew 66 and bolt 68, and extends rearwardly from said frame. Saidhandle'comprises a body portion H1 enclosing a water chamber 12,saidbody portion being ex- 5. A gummed tape applier comprising a frameadapted to carry a roll of gummed tape, a pressure wheel rotatablycarried by said frame whereby tape is drawn from said roll and appliedunder pressure to any surface with which said pressure wheel is rolledin contact, a moistening roller rotatably carried by said frame,engaging said pressure wheel and adapted to be driven thereby, a handleportion carried by said frame, said handle portion comprising a waterreservoir having a sealable filling opening and a cup portion extendingbeneath and partially encircling said moistening roller, and a resilientporous pad contained in said cup and formed to contact a portion of theperiphery of said moistening roller, said pad receiving water from saidreservoir through an opening provided in the forward wall of saidreservoir adjacent the bottom of said cup.

6. A gummed tape applier comprising a frame adapted to carry a roll ofgummed tape, a pressure wheel rotatably carried by said frame, wherebytape is drawn from said roll and applied under pressure to any surfaceon which said pressure wheel is rolled, a moistening roller of porousabsorbent material rotatably carried by said frame and operativelyengaging said pressure wheel, a handle portion carried by said frame,said handle portion comprising a water reservoir having a sealablefilling opening and a cup portion extending beneath and partiallyencircling said moistening roller, and a resilient porous pad containedin said cup and formed to contact a portion of the periphery of saidmoistening roller, said pad receiving water from said reservoir throughan opening provided in the forward wall of said reservoir adjacent thebottom of said cup.

7. A gummed tape applier comprising a frame adapted to carry a roll ofgummed tape, a pressure wheel rotatably carried by said frame wherebytape drawn from said roll is applied under pressure to any surface onwhich said pressure wheel is applied, means carried by said frame formoistening the gummed side or said tape before it is applied to saidsurface, a handle for said frame whereby said pressure wheel is manuallyrolled along said surface, and a blade carried movably by said frame andoperable by the movement of said handle toward the surface to which tapeis being applied to out said tape at any desired length.

8. A gummed tape comprising a frame adapted to carry a'roll of gummedtape, a pressure wheel rotatably carried by said frame whereby tapedrawn from said roll is applied under pressure to any surface on whichsaid pressure wheel is rolled, means carried by said frame formoistening the gummed side of said tape before it is applied to saidsurface, a handle for said frame whereby said pressure wheel is manuallyrolled along said surface, a cutting blade pivotally carried by saidframe adjacent the lower edge thereof and adapted for movement towardthe tape as it moved around said pressure wheel, whereby when saidhandle is moved toward the surface to which tape is being applied, theback of said blade is moved into contact with said surface, and thecutting edge of said blade is forced into contact with said tape on saidpressure wheel, cutting it off at any desired length.
